The moss - Family of Fontinalaceae consists almost exclusively of mosses that live submerged in the water (submerged). The other species need at least very wet locations. These are quite large, often 20–30 cm long, floating plants.

Since in the Fontinalaceae the apex cell does not rotate during growth, the original three-line foliage is preserved. The leaves are usually pointed or ovate and keeled with a sharp keel.

Since many species like to grow in fast-flowing waters, they very rarely form sporogons , because the probability of fertilization by the swimming spermatozoids would be very low. Sporogons are only formed in calm water. The propagation takes place via torn branches and trunks.

Genera

The family includes three genera:

In Europe there are two types : Dichelyma u. a. with Dichelyma camilaceum and Fontinalis a . a. with the spring moss ( Fontinalis antipyretica ).
